Abstract
A simple laser vaporization/photolysis technique capable of preparing a wide varity of organometallic free radicals for spectroscopic studies is described. It makes use of an excimer laser which vaporizes a metal sample and simultaneously photolyzes an organic precursor passing over the surface of the metal. The metal atoms and organic fragments then react to yield the organometallic species. Subsequent expansion into vacuum leads to extensive cooling of the molecules. In principle, this approach could be used to prepare a wide variety of gas-phase compounds of any metal. We will illustate its capabilities by presenting laser excitation spectra of several relatively simple organometallic radicals such as $CaCH_{3}$, $CdCH_{3}$, and $CaC_{3}H_{5}.$
